Hi,

That’s easy. Ctrl + right click a cell to change its color.

And they cause confusion because any green piece can go to any other green cell. In mycolor.png, there are only two green colors. And they don’t cause any confusion because a light green piece never go to the dark green cell and vice versa. All the light red/dark red, light blue/dark blue etc are similar.

I chose the 16-cell because it had relatively less colors. I love 24-cell but really hate distinguishing 24 colors. I cannot even name more than 10 major colors. At that time I studied the types of pieces in the 16-cell. But I didn’t start looking for algorithms.

One of the biggest breakthrough in searching for algos is, to find a convenient viewpoint. I don’t like the default view of 16-cell, where I can only see eight cells. I found that using ctrl+left click to center a cell gave a perfect viewpoint. So I setup my 3-cycle algorithms in that viewpoint. The second breakthrough is that I realized all 16 cells can be grouped into two groups. A sticker belonging to a group-A cell never goes to a group-B cell. So we don’t need 16 very different colors. We only need eight very distinct colors. And for the other eight I use the darker versions of the same colors. It took me some time to customize the colors. "Viewpoint" and "color pattern", two important things. Last night I worked very late and found algorithms needed to solve the small pieces around corners. Those are the hard part. I apparently missed the usual time to bed. The result is I couldn’t fall asleep till 5am. I don’t know if it’s excitation of the new puzzle or not.

In the 16-cell there are nine types of pieces. So six levels of rank cannot fully separate all nine types. In "rank 5+" there are three types of pieces, which leads to some difficulty seeing the inner corner pieces.
